My journey with My Bipolar II partner

Grrrr - I’m so angry and frustrated !!!!!!!! My partner (bipolar II rapid cycler) has just picked me up from the train station after work driving recklessly- she ran up over the curb ... I thought maybe an innocent error then overtook a reversing car, nearly hit a bus, ran over a traffic island and up onto another curb .... all of this within 30m of picking me up ... I was so mad I yelled at her to pull over and let me drive - I was soooo mad and still am that she didn’t tell me she was too exhausted to drive safely - I would have happily taken bus home or a taxi ... she knows that ... we have even talked about it - then I find out she has moved all our garden shed contents into the garage - a job she didn’t need to do today or on her own ... a huge job ... it needed doing as shed is being replaced in two days time but it exhausted her so much her fatigue afterwards makes her clumsy and unsafe with not just driving but also even doing things around the house - like moving her body around doing normal things without bumping into stuff etc .... this is not the first time she has over exhausted herself with jobs around the house and ended up driving dangerously or falling over etc as if drunk ... I’m sooo frustrated !!!!!!!! Any advice on what to do next ?????? How much can a person who is post hypo-manic and exhausted really understand ?? How much can a person with bipolar II be expected to self manage their exertion levels when feeling hypomanic to avoid over exertion and dangerous exhaustion levels ?? I don’t know what is reasonable to expect of my partner ??
